Twitter v. CNN: A New Media Watchdog

Twitter users blasted cable and Internet news organization CNN the past two days for a lack of coverage of the Tehran protests, which began after the election in Iran, reports Mashable:

“Twitter… has… taken on the role of media watchdog: thousands of Twitter users adopted the hashtag #CNNfail to highlight a lack of Iran coverage from the... organization.”

As a result, CNN quickly stepped up TV coverage of the Iranian election and the CNN.com homepage now lists the protests as its top story.
